I bought a Keeper (didn't know about the controversy at the time) before my last cycle and while it worked fairly well, I still was getting seepage - nothing that a small pantyliner couldn't handle, but annoying nonetheless. I thought I knew my body pretty well, but with this cup, I felt about as clueless as a teenage boy. I had no intention of going back to tampons, but I hadn't yet figured out how I was going to deal with the leakage when swimming.
Thank you, thank you for the help on how to measure myself and on the different menstrual cup options I have in the U.S.! I am highly hopeful that I can find a cup that works properly for my unique body, since I'm doubting it's going to be the Keeper.
